Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`static ArrayType`	`construct(JavaType componentType, TypeBindings bindings)`
`static ArrayType`	`construct(JavaType componentType, TypeBindings bindings, Object valueHandler, Object typeHandler)`
`boolean`	`equals(Object o)`
`JavaType`	`getContentType()`	Method for accessing content type of this type, if type has such a thing: simple types do not, structured types do (like arrays, Collections and Maps)
`Object`	`getContentTypeHandler()`	Internal accessor that should not be used by any code outside of jackson-databind: only used internally by databind.
`Object`	`getContentValueHandler()`	Internal accessor that should not be used by any code outside of jackson-databind: only used internally by databind.
`Object[]`	`getEmptyArray()`
`StringBuilder`	`getErasedSignature(StringBuilder sb)`	Method for accessing signature without generic type information, in form compatible with all versions of JVM, and specifically used for type descriptions when generating byte code.
`StringBuilder`	`getGenericSignature(StringBuilder sb)`
`boolean`	`hasGenericTypes()`	Method that can be used to find out if the type directly declares generic parameters (for its direct super-class and/or super-interfaces).
`boolean`	`hasHandlers()`	Helper method that checks whether this type, or its (optional) key or content type has `JavaType.getValueHandler()` or `JavaType.getTypeHandler()`; that is, are there any non-standard handlers associated with this type object.
`boolean`	`isAbstract()`	For some odd reason, modifiers for array classes would claim they are abstract types.
`boolean`	`isArrayType()`
`boolean`	`isConcrete()`	For some odd reason, modifiers for array classes would claim they are abstract types.
`boolean`	`isContainerType()`
`JavaType`	`refine(Class<?> contentClass, TypeBindings bindings, JavaType superClass, JavaType[] superInterfaces)`	Mutant factory method that will try to create and return a sub-type instance for known parameterized types; for other types will return `null` to indicate that no just refinement makes necessary sense, without trying to detect special status through implemented interfaces.
`String`	`toString()`
`JavaType`	`withContentType(JavaType contentType)`	Mutant factory method that may be called on structured types that have a so-called content type (element of arrays, value type of Maps, referenced type of referential types), and will construct a new instance that is identical to this instance, except that it has specified content type, instead of current one.
`ArrayType`	`withContentTypeHandler(Object h)`	Internal method that should not be used by any code outside of jackson-databind: only used internally by databind.
`ArrayType`	`withContentValueHandler(Object h)`	Internal method that should not be used by any code outside of jackson-databind: only used internally by databind.
`ArrayType`	`withStaticTyping()`	Method that can be called to get a type instance that indicates that values of the type should be handled using "static typing" for purposes of serialization (as opposed to "dynamic" aka runtime typing): meaning that no runtime information is needed for determining serializers to use.
`ArrayType`	`withTypeHandler(Object h)`	Internal method that should not be used by any code outside of jackson-databind: only used internally by databind.
`ArrayType`	`withValueHandler(Object h)`	Internal method that should not be used by any code outside of jackson-databind: only used internally by databind.

If content type is already set to given type, this is returned. If type does not have a content type (which is the case with SimpleType), IllegalArgumentException will be thrown.
